BACKGROUND: Bioprosthetic (BP) valves have been increasingly used for aortic valve replacement over the last decade. Due to their limited durability, patients presenting with failed BP valves are rising. Valve in Valve - Transcatheter Aortic Valve Implantation (ViV-TAVI) emerged as an alternative to the gold standard redo-Surgical Aortic Valve Replacement (redo-SAVR). However, the utility of ViV-TAVI is poorly understood. METHODS: A systematic electronic search of the scientific literature was done in PubMed, EMBASE, SCOPUS, Google Scholar, and ClinicalTrials...

Current guidelines recommend dual-antiplatelet therapy (DAPT) after transcatheter aortic valve implantation (TAVI), although some studies suggest mono-antiplatelet therapy is equally efficacious with an improved safety profile. We performed a meta-analysis of studies comparing DAPT with mono-antiplatelet therapy after TAVI. Study quality and heterogeneity were assessed using Jadad score, Newcastle-Ottawa Scale, and Cochran's Q statistics. Mantel-Haenszel odds ratios (ORs) were calculated using fixed effect models as the primary analysis...

Transcatheter valve-in-valve implantation (ViV-TAVI) has evolved as an alternative to redo surgical valve replacement (redo-SAVR) for high-risk patients with aortic bioprosthetic valve (BPV) dysfunction. The differences in procedural success and outcomes in a large number of patients who underwent ViV-TAVI compared with redo-SAVR for aortic BPV dysfunction are not known. We conducted a meta-analysis of the previously reported studies to determine outcomes after ViV-TAVI and redo-SAVR. PubMed, MEDLINE, and Google Scholar databases were searched for studies that reported comparative outcomes of patients who underwent either ViV-TAVI or redo-SAVR...

A patient presented with a decompensated cardiomyopathy requiring invasive hemodynamic support with an Impella® heart pump. Extracorporeal life support (ECLS) became necessary during the further course and the patient was bridged to left ventricular assist device (LVAD) implantation. Postoperatively, the patient did not improve as expected due to new aortic regurgitation (AR) that was most likely caused by the previously placed Impella. A SAPIEN 3 transcatheter aortic valve was implanted as a bail-out strategy; an additional valve-in-valve rescue was required due to paravalvular regurgitation...

BACKGROUND: The clinical robustness of contrast-videodensitometric (VD) assessment of aortic regurgitation (AR) after transcatheter aortic valve implantation (TAVI) has been demonstrated. Correct acquisition of aortic root angiography for VD assessment, however, is hampered by the opacified descending aorta and by individual anatomic peculiarities. The aim of this study was to use preprocedural multi-slice computed tomography (MSCT) to optimize the angiographic projection in order to improve the feasibility of VD assessment...

Access challenges are sometimes encountered in patients who require transcatheter aortic valve implantation (TAVI). Transapical (TA) access is a well-established alternative, but it is more invasive than the standard transfemoral (TF) access techniques. We adopted the iliac endoconduit technique to perform TF TAVI in a patient with small-caliber, heavily calcified iliac arteries. This technique could provide an adequate access route for TAVI that is minimally invasive, even for patients with prohibitory iliac anatomy...

Mitroflow aortic prosthesis dysfunction in case of complex vascular disease is considered a challenging scenario. Because of the high risk for surgical reoperation and the presence of chronic aortic dissection originated from a calcified Kommerel diverticulum, we considered to perform a transapical valve-in-valve transcatheter aortic valve implantation (TAVI) procedure. Myocardial ischemia is a dreadful complication reported in valve-in-valve TAVI procedures, mainly in patients with degenerated Mitroflow aortic bioprostheses...

BACKGROUND: The extent of aortic valve calcification is an important determinant of procedural success in transcatheter aortic valve implantation (TAVI). We sought to validate device landing zone calcium volume (DLZ-CV) measurements on contrast-enhanced multidetector computed tomography (MDCT) with non-contrast-enhanced scans as reference. METHODS: We determined DLZ-CV in 141 patients undergoing transfemoral TAVI. Non-contrast-enhanced images were analyzed using a threshold of 130 HU as reference (DLZ-CV130 )...

BACKGROUND: Symptomatic aortic stenosis has a poor prognosis. Many patients are considered inoperable or at high surgical risk for surgical aortic valve replacement (SAVR), reflecting their age, comorbidities and frailty. The clinical effectiveness and safety of TAVI have not been reviewed systematically for these high levels of surgical risk. This systematic review compares mortality and other important clinical outcomes up to 5 years post treatment following TAVI or other treatment in these risk groups...

Introduction: Transcatheter aortic valve implantation (TAVI) improves prognosis in patients disqualified from surgical valve replacement. Calcifications of the aortic complex can lead to deformation of the prosthesis, resulting in paravalvular leaks (PVL). Aim: To evaluate the predictive value of quantitative estimation of volume/weight and geometric distribution of calcifications in multislice computed tomography, for the development of PVL. Material and methods: This was a retrospective, case-control study on patients with a CoreValve aortic prosthesis...

AIMS: Long-term results of transcatheter aortic valve implantation (TAVI), in particular the incidence of bioprosthetic valve failure (BVF), are uncertain. METHODS AND RESULTS: The study prospectively included all 152 patients who had undergone TAVI with the self-expanding CoreValve™ up to December 2011 at the Heart Center, Bad Segeberg, Germany. Late BVF (>30 days) was defined as either: 1) Severe structural valve deterioration (trans-prosthetic mean pressure gradient ≥40 mmHg and/or ≥20 mmHg rise from baseline OR severe intra-prosthetic aortic regurgitation), OR 2) Bioprosthetic valve dysfunction leading to death or re-intervention...

AIMS: Risk assessment tools currently used to predict mortality in transcatheter aortic valve implantation (TAVI) were designed for patients undergoing cardiac surgery. We aim to assess the accuracy of the TAVI dedicated American College of Cardiology / Transcatheter Valve Therapies (ACC/TVT) risk score in predicting mortality outcomes. METHODS AND RESULTS: Consecutive patients (n=1038) undergoing TAVI at a single institution from 2014 to 2016 were included. The ACC/TVT registry mortality risk score, the Society of Thoracic Surgeons - Patient Reported Outcomes (STS-PROM) score and the EuroSCORE II were calculated for all patients...

The main limitation of bioprosthetic valves is their limited durability, which exposes the patient to the risk of aortic valve reintervention. Transcatheter aortic valve implantation (TAVI) is considered a reasonable alternative to surgical aortic valve replacement (SAVR) in patients with intermediate or high surgical risk. TAVI is now rapidly expanding towards the lower risk populations. Although the results of midterm durability of the transcatheter bioprostheses are encouraging, their long-term durability remains largely unknown...

BACKGROUND: Aortic valve calcification patterns were associated with short- and long-term outcomes in previous small observational datasets of patients undergoing transcatheter aortic valve implantation (TAVI). The specific impact of multi detector-row computed tomography (MDCT) findings on outcomes in women has not been reported. We sought to describe the associations between MDCT characteristics and clinical outcomes in a registry of 547 women undergoing TAVI. METHODS: WIN-TAVI is the first all-female registry to study the safety and effectiveness of TAVI in women (n = 1019)...

The relation between C-reactive protein (CRP) level on admission and mortality after transcatheter aortic valve implantation (TAVI) remains unclear. To evaluate the impact of serum CRP level on mortality after TAVI, we assessed 1,016 patients with CRP who underwent TAVI and 538 patients with high-sensitive CRP (hs-CRP) level who underwent TAVI on admission in the OCEAN (Optimized Transcatheter Valvular Intervention)-TAVI registry. Study population was stratified into 2 groups (high/low), according to the median of CRP and hs-CRP on admission...
